Hi, Hockeymom, welcome to NeuroTalk. I agree that an appointment with a neurologist can only be a good thing. Worst case, your son is sent home with a clean bill of neurological health and that would be dandy.

Several of my friends' kids have gone through the sudden, dramatic growth spurts and experienced multiple body changes sumultaneously. All survived it, but definitely had some strange patches that included growing pain, mood swings, childish neediness, anger, some confusion, bouts of lightheadedness, fatigue, and many other things. Add hormones to the mix and it's quite a bag of tricks.

I don't mean to trivialize your concerns, I do believe the rink whollop may have racked him. The head-bounce within a helmet can be as devastating as a blunt-force trauma.

Please do see the neuro, and please do visit the concussion talks. I wish you well.
